How to make atari audio rom sounds

[walters]

How do i make the atari audio rom sounds?

 

Do i have to write code to trigger the sounds off the rom chip?

 

Or Is their code to set the Attack,decay of the audio sounds?

 

What are the setting for the audio sounds for code?

 

Every game has different sounds why is that how did the programmer

do this to have different sounds? how do i do this to program different

sounds?

Yes.

 

Or Is their code to set the Attack,decay of the audio sounds?

No.

 

What are the setting for the audio sounds for code?

Read the docs please (e.g. Stella Programmers Guide).

The 2600,7800,5200 system have different sound card rom chips right?

is this hardware sound card rom chips? inside the these systems?

 

How do i trigger these sounds on the 2600,7800,5200 without a game card

do i use voltages on the sound card "pins"?

No, it's an ASIC called the TIA.

Sort of, but it's not a good idea.

 

It's possible pull the TIA out of the 2600, build a state machine (or use a microcontroller) to write to its internal registers and capture the audio at the output, but this would be really hard to do, and not worth the effort, since the TIA is not very good as a general purpose sound chip, especially compared to what's available today.

You need to learn to program these machines. You create sounds by programming registers that control the sound generation hardware.
